GPGPU in the brain: neuroscientist-approved transhumanism

I haven't been able to find a single neuroscientist publicly agree with Ray Kurzweil that either neuroscience-based AI or brain-computer interfaces are likely to progress far enough this century to lead to a singularity.

Given all this cause for pessimism, and the weight of scientific consensus apparently behind it, I was pleased to read that a prominent neuroscientist -- especially one who's been an outspoken critic of both Ray Kurzweil and IBM's artificial-brain projects -- had recently predicted a transhuman revolution. I was even more pleased when I realized the source of that revolution was analogous to a computing technology I'm studying for my master's thesis: general-purpose computation on graphics-processing units (GPGPU).
